According to multimedia service distribution such as High-Definition TeleVision (HDTV), Internet Protocol TeleVision (IPTV) and Voice Over Internet Protocol (VoIP), the networks are required to guarantee Quality of Service (QoS) and real-time performance. Power Line Communication Technology is used for data transfer as well as the transfer of electric power. However, power line communication has some problems in wireless communication such as a noise and hidden station problem. And MAC cycle is synchronized with AC cycle of power line. MAC scheme is week in real time data transmission with short cycle. Therefore, in this paper, the authors propose a new MAC scheme for real-time service. Proposed scheme uses new message called TRINFO.
